I need a "good" thumbnail generator for Mac. Any suggestions?

Some criteria:

  • Must support common image formats(ie png,jpg,etc.).
  • Easy to use.
  • Support large image files.
  • Free and/or not crippled.
  • Must be able to do files and directories if needed.

The software's sole purpose should be to output thumbnails.

Thanks!

Is there a particular purpose for said thumbnail generator? – digitxp Nov 16 '10 at 22:47
@digitxp - I'm currently working on something where I have hundreds of large jpgs and I need to get them in a thumbnail size and in various formats. I need a non-tedious way to accomplish this. – ricbax Nov 16 '10 at 23:01
How about Automator? – Daniel Beck Nov 16 '10 at 23:09

I would use ImageMagick for this. Here's a link to the OS X installation instructions. It is certainly not its sole purpose to generate thumbnails, but you can script a command for this based on numerous examples at the ImageMagick website. An example command would be:

convert -define jpeg:size=500x180  hatching_orig.jpg  -auto-orient \
      -thumbnail 250x90   -unsharp 0x.5  thumbnail.gif

Batch processing can be achieved using something like:

mogrify  -path thumbnails -thumbnail 100x100  *

These are only examples and you should check all the ImageMagick options relevant to the images that you will be processing.

+1 Any other programs suggested may very well do the same thing by using ImageMagick to do it. – paradroid Nov 17 '10 at 1:23
Not quite too far up on the 'easy to use' category though. – digitxp Nov 18 '10 at 12:37
Personal opinion, but on the contrary, I find this easiest to use. – fideli Nov 18 '10 at 14:16

http://ddd.ee/NIT_bulk_resize_and_watermark/ Works on Mac and Windows exactly the same, requires Adobe Air but it's autmatically installed.

Shameless plug - My software ImageXY might be perfect for you - does everything that you want without the overly complex interface that most image resizers have.
